[QUOTE="messydesk, post: 3004236, member: 1765"]Who disturbs my slumber?! Anyway, there are R-numbers assigned to specific Morgan dollar varieties, but they need to be taken with a grain of salt. When the VAM book was first written, the scale was pretty much a log base 10 scale, where R-n meant less than 10^(9-n). Since obviously no dies made tens of millions of coins, R-1 was used for the generic 1921 variety. This is before the series was studied down to the every die for every date level of detail. Now your average VAM is probably R-4 or 5, when you consider attrition, if you use that scale. These numbers are estimates based on how likely it is that a coin with a given feature should have been noticed by now and, if the listing is for some sort of die damage, how long the die was probably in the condition it was in when the coin was struck. GSA Morgans in general don't have R-numbers, but the VAMs that show up in GSA holders do. A few are rare, most are not (given the definition or rare). The production numbers above are what you'd need to know when buying them. I rather dislike Bowers' URS scale, but that's a topic for (or from) a different thread.[/QUOTE]
